A power amplifier arrangement having a distributed antenna is disclosed.
The power amplifier arrangement has two or more signal paths which are
coupled to a common input. Each signal path has an amplifier with a
downstream antenna. The respective signal paths with the antenna are
activated or deactivated by a control device as a function of the desired
gain or output power. This results in high efficiency over a wide
frequency range. The polar diagrams of the antenna branches preferably
correspond to those of a single antenna.
